Abstract

The invention relates to a preparation method for a natural fiber-containing modified car trim. The preparation method includes the following steps: (1) preparation of materials; (2) preparation of biomass powder: Natural fiber-containing biomass is milled into powder by a ball mill, the powder is dried, and thereby biomass powder is obtained; (3) modification of biomass powder: The biomass powder prepared in step (2) is poured into a high-speed mixer, meanwhile, an additive and ore powder are added in, premixing is carried out, heating is carried out for drying, the heating temperature is 70 DEG C to 170 DEG C, the heating time is 10 to 15 minutes, and thereby modified biomass powder is obtained; (4) mixing and pelletization: The obtained modified biomass powder and polypropylene (PP) are mixed and pelletized in pelletization equipment, and the pelletization temperature is 165 DEG C to 250 DEG C; (5) injection molding: The obtained biomass-modified PP material and a PP injection-molding production material are mixed and added with an additive, injection molding and product preparation are carried out, and thereby the biomass-containing modified plastic car trim is obtained.

Description

technical field [0001] The invention relates to a preparation method and application of a modified automobile decoration containing natural fibers. Background technique [0002] At present, the automotive trims on the market mainly include metal, plastic and plastic textures, or their composite materials. Among them, the price of metal is relatively high, the texture is hard, the processing performance is poor, the weight is heavy, and there are hidden dangers of rust and leakage. In comparison, most manufacturers currently start to use plastic materials for automotive trim parts, which are prepared by injection molding. Through modification and enhancement, most plastic automotive decorative parts have the functions of flame retardancy, antistatic, waterproof, corrosion resistance and even impact. However, all-plastic automotive trims still have shortcomings in terms of poor air permeability, low strength, easy aging, poor recyclability, and high cost. In view of the abo...
